1. **State the problem:**
We need to solve for $n \in \mathbb{N}$ the equation
$$ (\log_2 3)(\log_3 4)(\log_4 5) \cdots (\log_{n-1} n)(\log_n (n+1)) = 11. $$
2. **Recall the change of base formula and telescoping property:**
Using the change of base formula,
$$ \log_a b = \frac{\log_c b}{\log_c a} $$
for any positive base $c \neq 1$.
3. **Simplify the product using telescoping:**
Observe that
$$ (\log_2 3)(\log_3 4) = \frac{\log 3}{\log 2} \times \frac{\log 4}{\log 3} = \frac{\log 4}{\log 2} = \log_2 4. $$
Similarly,
$$ (\log_2 3)(\log_3 4)(\log_4 5) = \log_2 5, $$
and so on.
4. **Generalize the telescoping product:**
The entire product simplifies to
$$ (\log_2 3)(\log_3 4) \cdots (\log_n (n+1)) = \log_2 (n+1). $$
5. **Set the simplified expression equal to 11:**
$$ \log_2 (n+1) = 11. $$
6. **Solve for $n$:**
Rewrite in exponential form:
$$ n+1 = 2^{11}. $$
Calculate:
$$ n+1 = 2048 \implies n = 2047. $$
**Final answer:**
$$ \boxed{2047} $$
This means the value of $n$ that satisfies the equation is 2047.
